Amino Acid is one of several molecules that join together to form proteins. There are 20 common amino acids found in proteins.

Key survival circuit discovered in Salmonella bacteria

Hundreds of trillions of bacteria make their home in the vertebrate gut. Though many of these microbes perform helpful duties for their host, others - the pathogens - are unwelcome visitors, causing disease.

Defective calcium metabolism in nerve cells contributes to neurological disorder

Defective calcium metabolism in nerve cells may play a major role in a fatal genetic neurological disorder that resembles Huntington's disease, researchers at UT Southwestern Medical Center have found in a mouse study.

Gut found to exert control over bone

When it comes to remodeling our bones-an ongoing process of break down and renewal that goes on throughout adulthood--researchers have new evidence that our guts play a surprisingly important role.

Understanding donor-recipient genetics could decrease early kidney transplant complications

Researchers at the University of Pennsylvania School of Medicine have found an association between the genetics of donor-recipient matches in kidney transplants and complications during the first week after transplantation.

First-ever glimpse of the cell-wall structure in three dimensions

The bacterial cell wall that is the target of potent antibiotics such as penicillin is actually made up of a thin single layer of carbohydrate chains, linked together by peptides, which wrap around the bacterium like a belt around a person, according to research conducted by scientists at the California Institute of Technology (Caltech).

New clue for cellular damage in Huntington's disease

"Huntington's disease presents an ideal vantage point to study neurodegenerative disease, because we know the misfolded protein that's responsible," says Martin Duennwald, formerly a postdoctoral researcher in the lab of Whitehead Member Susan Lindquist.

Scientists map steps to block enzyme phosphodiesterase 5's action in heart failure

Taking a cue from the way drugs like Viagra put the biological brakes on a key enzyme involved in heart failure, scientists at Johns Hopkins have mapped out a key chemical step involved in blocking the enzyme.

Folic acid does not offer any cardiovascular benefits

Folic acid is safe - but it lacks any cardiovascular benefits - according to researchers presenting at the American Heart Association's Scientific Sessions 2008. The results from the Study of the Effectiveness of Additional Reductions in Cholesterol and Homocysteine (SEARCH), a 12,064-person, randomized study, were presented as a late-breaking clinical trial.

Researchers discover metabolic deficiency in pancreatic cancer

UC Davis Cancer Center researchers have discovered a metabolic deficiency in pancreatic cancer cells that can be used to slow the progress of the deadliest of all cancers.

Beta-alanine supplement shows strong effects in the elderly

Beta-alanine (BA), a dietary supplement widely used by athletes and body builders, has been proven to increase the fitness levels of a group of elderly men and women.

Scientists confirm a molecular clipping mechanism behind stem cell development

Stem cells don't just become a part of the liver or the brain in a flash; it takes a complex molecular choreography and requires that specific genes be switched on and off at specific times.

Targeting epigenetic changes helps tackle MLL-AF4 leukemias

A very difficult-to-treat child leukemia may benefit from the discovery of a small but potent epigenetic change that launches the cancer - but could potentially be reversed relatively easily, preventing cancer-promoting genes from being turned on.

Sunshine could help fix male infertility

Australian fertility experts say a dose of daily sunshine could help men with fertility problems and they suggest couples struggling to conceive should consider getting out in the sunshine more often.

High-dose vitamin B supplements do not slow cognitive decline in Alzheimer's

A clinical trial led by Paul S. Aisen, M.D., professor of neurosciences at the University of California, San Diego School of Medicine, showed that high-dose vitamin B supplements did not slow the rate of cognitive decline in patients with mild to moderate Alzheimer disease.

Study specifies chemical pathway for ions through the cell membrane

Life ultimately depends on the traffic of tiny charged particles through porous proteins studding the membrane surrounding every cell. In research published in Nature, scientists at The Rockefeller University have for the first time mapped a stepping-stone pathway of amino acids that these charged particles, or ions, follow across cell membranes.
